I want to thank everybody that has stood by me and shown me huge support -- the management, my team-mates and the fans."

"I want to let everyone know that I will give everything I have to repay them and deliver success over the years to come. I'm still very young with a lot more to learn and I can't wait to continue my progress under Jose Mourinho."
